Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a multiple transmission remote control device that controls lighting, etc. using multiple transmission signals.

[Background technology]

Conventionally, multiplex transmission consists of an operating device that sends out multiplexed transmission signals by operating a switch, and a control terminal that is connected to the operating device via a transmission line and reverses the operation of the load each time the multiplexed transmission signal is called. In order to control lighting and the like in a remote control device, it is necessary to have a function such as being able to temporarily turn on the light in a place where the device is used, such as a hallway. Therefore, in order to control lighting and the like using multiplex transmission equipment, it is necessary to provide a specific channel for a temporary lighting switch, and as the functionality increases, the number of channels increases accordingly. Another drawback was that if the functionality could not be increased any further, the entire system would have to be redesigned.

[Purpose of invention]

The present invention was devised in view of the above-mentioned problems, and its purpose is to provide a multiplex transmission remote control device that can reduce the number of transmission signal channels and facilitate system expansion.

[Disclosure of invention]

1 and 2 are diagrams showing an embodiment of the present invention, including a temporary lighting switch SW ₁ , a remote control switch SW ₂ , a latch means for keeping the switch SW 1 in the ON state, and a latch means for keeping the switch SW ₁ in the ON state. Counting means 2 starts counting with the output of , and resets the latch means by outputting one pulse after counting for a predetermined time, and resets the count with the output of the latch means that occurs when switch SW ₂ is turned on and reset. It consists of a reset means, an OR circuit for performing a logical sum of the outputs of both switches SW ₁ and SW ₂ and the counting means 2, and a signal processing circuit 5 for converting the output of the OR circuit into a multiplexed transmission signal. Here, the latch means is constituted by a flip-flop FF, and the counting means 2 is constituted by a flip-flop FF.
It consists of an AND circuit 7 that performs a logical product of the non-inverted output Q of the FF and the output of the oscillation circuit 6, and a counter 8 that counts the output of the AND circuit 7. reset, flip-flop FF
It is composed of an OR circuit 3 which outputs an H level when the inverted output of the switch SW ₂ becomes an H level and when the switch SW ₂ side becomes an H level when the switch SW 2 is turned on.

The operation of the above-described embodiment of the present invention will be explained with reference to the time chart shown in FIG. When _the switch SW ₁ is turned on as shown in FIG. Sends a converted signal. In response to this signal, a control terminal such as a lighting device performs an operation such as turning on a lighting device, as shown in FIG. Also switch
When _SW1 is turned on, the non-inverted output Q of the flip-flop FF becomes H level as shown in FIG. An AND circuit 7 performs a logical product of this H level signal and the output of the oscillation circuit 6. That is, the oscillation circuit 6 repeats on and off at a constant cycle, and the AND circuit 7
A pulse having the same period as the output of the oscillation circuit 6 is generated at the output. The output pulses of the AND circuit 7 are counted by a counter 8. When the counter 8 counts a predetermined number of pulses set in advance, the counter 8 outputs one pulse at the H level as shown in d of the figure. This pulse passes through the OR circuit 4, and as shown in FIG.
The code is input to the terminal device for controlling lighting, etc. via the transmission line 6 with the same code as when switch SW ₁ is turned on, and as shown in Figure 2e, it is the opposite of the code input above. Turn off the lights. Further, the output of the counter 8 is input to the reset terminal of the flip-flop FF, and resets the flip-flop FF, causing the non-inverted output Q to be at L level and the inverted output to be at H level. The H level of the inverted output at this time is input to the reset terminal of the counter 8 via the OR circuit 2 to reset the count.

Next, when the switch SW ₂ is turned on by an external circuit or the like as shown in FIG. 2 f, this on-pulse is inputted to the signal processing circuit 5 via the OR circuit 4 as shown in FIG. The code is converted into the same code as the switch _SW1 , and lights, etc. are turned on via the transmission line 6 as shown in the figure e. The on-pulse of the switch _SW2 is input to the reset terminal of the counter 8 via the OR circuit 3, and the counting operation of the counter 8 is reset. That is, even when the switch _SW1 is pressed and the counter 8 is counting for a predetermined time, it is forcibly reset. If it is desired to turn off the illumination, the switch SW ₂ is turned on again as shown in FIG. 2f, and the illumination is turned off as shown in FIG. As described above, in this embodiment, the illumination can be turned on temporarily or constantly using the output code of the same signal processing circuit 5.

[Effect of idea]

The present invention includes a first switch, a second switch, a latch means for keeping the first switch in the on state, and a count is started by the output of the latch means, and one pulse is output after a predetermined time has been counted. a count means for outputting and resetting the latch means; a reset means for resetting the counter with the output of the latch means generated when the second switch is turned on and reset; an OR circuit for performing a logical sum of the outputs of both the switches and the counter; Since it has a signal processing circuit that converts the output of the OR circuit into a signal for transmission, lighting equipment etc. can be turned on by turning on the first switch, turning on and off the second switch, and output pulses from the counter. , can be turned off. In other words, lighting equipment can be turned on and off by the signal processing circuit outputting a single signal with the same pulse, so if the above-mentioned switch operations are made into individual signals as in the past, Since the number of signal types can be reduced, the number of channels can be reduced, and even after the construction of the system is completed, it is easy to add controllers for multiplex transmission and remote control.
